砂仁叶枯病菌生长发育温度是10～38℃,孢子发芽温度为5～38℃,而以20～35℃萌发较好。致死温度54℃10分钟。孢子萌发要求RH96%以上的高湿度,饱和湿度最佳。病菌在pH3.1～11.05之间都能生长,在pH5.22～10.13时产孢量较多,孢子萌发率则在pH5.0～8.0时为高。砂仁果浸出液能刺激孢子发芽。病菌存活期在16个月以上。该菌对多种单糖、双糖、多糖都能利用,而氮源则以硝态氮和氨基酸态氮利用较好,氨态氮抑制病菌生长。该菌对碳、氮源的利用还受光照条件的影响。
The growth and development temperature of Amorpha fruticosa is 10 ~ 38 ℃, the spore germination temperature is 5 ~ 38 ℃, while the germination is better at 20 ~ 35 ℃. Lethal temperature 54 ℃ 10 minutes. Spore germination requirements RH96% of the high humidity, the best saturation humidity. The pathogen could grow between pH3.1 and 11.05, sporulation rate was higher at pH5.22 ~ 10.13, and spore germination rate was higher at pH5.0 ~ 8.0. Amomum leachate spores can stimulate sprouting. Germ survival of 16 months or more. The bacteria for a variety of monosaccharides, disaccharides, polysaccharides can be used, while the nitrogen source nitrate nitrate and amino acid nitrogen is better, ammonia nitrogen inhibition of bacteria growth. The use of carbon and nitrogen sources by the bacteria is also affected by lighting conditions.
